The ADP5072 is a dual, high performance dc-to-dc regulator that generates independently regulated positive and negative rails.
The input voltage range of 2.85 V to 5.5 V supports a wide variety of applications. The integrated main switch in both regulators enables generation of an adjustable positive output voltage up to 35 V and a negative output voltage down to −30 V.
The ADP5072 operates at a pin selected 1.2 MHz or 2.4 MHz switching frequency. The ADP5072 can synchronize with an external oscillator from 1.0 MHz to 2.6 MHz to ease noise filtering in sensitive applications. Both regulators implement programmable slew rate control circuitry for the MOSFET driver stage to reduce electromagnetic interference (EMI). Flexible start-up sequencing is provided with the options of manual enable, simultaneous mode, positive supply first, and negative supply first.
The ADP5072 includes a fixed internal or resistor programmable soft start timer to prevent inrush current at power-up.
Other key safety features in the ADP5072 include overcurrent protection (OCP), overvoltage protection (OVP), thermal shutdown (TSD), and input undervoltage lockout (UVLO).
The ADP5072 is available in a 20-ball WLCSP and is rated for a −40°C to +125°C junction temperature range.
